Soil water status and water table depth modelling using electromagnetic surveys for precision irrigation scheduling
Electromagnetic surveys have been used to quantify soil variability with respect to soil water storage in an irrigated maize field. A fluctuating water table sub-irrigates the crop in some places, and a wireless sensor network simultaneously monitors real-time depth of water table and so... Read More
Agronomic and socio-economic analysis of water management techniques for dry season cultivation of common bean in Malawi.
A study was carried out in Malawi to compare agronomic and socio-economic aspects of different water management practices for two advanced bean lines. Four irrigation technologies and one control were studied in Chingale Area Development Program in Zomba District in southern Malawi. T... Read More
Managing soils to achieve greater water use efficiency: A review
Water use efficiency (WUE) represents a given level of biomass or grain yield per unit of water used by the crop. With increasing concern about the availability of water resources in both irrigated and rainfed agriculture, there is renewed interest in trying to develop an understandin... Read More
Use of best management practices to increase nitrogen use efficiency and protect environmental quality in a broccoli-corn rotation of Central Mexico
Underground water reserves in Central Mexico have been declining and NO3--N concentrations of some irrigation wells have been found to exceed 10 ppm. There is the need to develop best management practices (BMPs) that can increase N and water use efficiency by vegetables such as brocco... Read More
IMPORTANCE OF SOIL AND CROPPING SYSTEMS IN THE DEVELOPMENT OF REGIONAL WATER-QUALITY POLICIES
Targeting certain soils and cropping systems may be necessary in consideration of regional water quality protection policies. However, little information is available relating soils and cropping practices to regional water quality problems. This study evaluates crop yield and NO3-N mo... Read More
Water saving in rice-wheat systems
Water shortage is a major constraint to sustaining and increasing the productivity of rice-wheat systems. Saving water can be elusive in that reducing seepage, percolation and runoff losses from fields does not necessarily save water if it can be recaptured at some other temporal or s... Read More
Crop simulation models can be used as dryland cropping systems research tools
Dryland cropping systems research in the semiarid Great Plains region requires a substantial investment in land, labor, and other resources. The objective of this analysis was to illustrate that crop simulation models can assist scientists in making more efficient use of these resourc... Read More
